Products classified under HTS 2529.22.00.00
Acid Grade Fluorspar Lump
High-purity fluorspar lumps containing over 97% calcium fluoride, mined and crushed for industrial use in hydrofluoric acid production. This raw material falls under HTS 2529.22.00.00 due to its exceptional calcium fluoride content exceeding 97% by weight, distinguishing it from lower-grade fluorspar.
Metallurgical Grade Fluorspar Powder
Finely ground fluorspar powder with >97% CaF2 content, used as a flux in steelmaking to lower melting points. Classified under HTS 2529.22.00.00 for its high calcium fluoride purity in raw, unprocessed mineral form.
High-Purity Fluorspar Chips
Chipped fluorspar pieces exceeding 97% calcium fluoride by weight, ideal for aluminum smelting fluxes. This product is specifically under HTS 2529.22.00.00 as natural fluorspar meeting the high-purity criterion.
Optical Grade Fluorspar Crystals
Natural fluorspar crystals selected for >97% CaF2 purity, used in lens manufacturing and spectroscopy. Falls under HTS 2529.22.00.00 as unworked high-purity fluorspar mineral.
Ceramic Flux Fluorspar Granules
Granulated fluorspar with over 97% calcium fluoride, serving as a flux in ceramic tile production. Classified in HTS 2529.22.00.00 for its natural high-purity state before processing.
Hydrofluoric Acid Feedstock Fluorspar
Premium lump fluorspar exceeding 97% CaF2, specifically graded for hydrofluoric acid synthesis. HTS 2529.22.00.00 applies to this raw, high-concentration natural mineral.
Steel Flux High-Purity Fluorspar
Crushed fluorspar chunks >97% CaF2 used as slag former in electric arc furnaces. This raw material is classified under HTS 2529.22.00.00 based on its superior calcium fluoride content.
Aluminum Reduction Fluorspar Briquettes
Briquetted fluorspar >97% CaF2 for use in aluminum electrolysis cells as electrolyte component. Remains under HTS 2529.22.00.00 as agglomerated natural high-purity mineral, not chemically altered.
Glass Manufacturing Fluorspar
Fine-ground fluorspar powder containing more than 97% calcium fluoride for glass opacity and fluxing. HTS 2529.22.00.00 covers this essential high-purity raw material for container glass production.
Chemical Grade Fluorspar 98%
Premium chemical-grade fluorspar assayed at 98%+ CaF2 for fluorine compound synthesis. Specifically classified under HTS 2529.22.00.00 for exceeding the 97% purity threshold.
